- Application filed May 15,

The object of our invention is to provide a-needle of this class and'character wh ch may. be used repeatedly with little or no alteration and which will last indefinitely,

practicallyeliminate scratching, and accurately render the sounds of the phonograph to which it is attached. This and other objects are accomplished by our invention, one

' embodiment of which lis hereinafter more particularly setforth; v 1 For a more detailed. description of our invention, reference is to be had to the accent panying drawings, forming a part hereof, in which Figure v1 is a side elevation of a needle em bodying our invention,'a part being broken away to reveal tl16TSlZ1LlCl3l1T8.

Figure 2 is a sectional ,view, taken on the line 22 of Figure 1, looking in the direction of the arrows.

FigureB is a perspective view of this needle, and

Figure 4 shows a needle in place in an 7 ordinary phonograph.

- Figure 5 shows a modification.

. Throughout the various views of; the

drawings, similar reference oharacters designate similar parts. w

i a Our improved needle lcomprises a holder .2 and a wire 3 which is adapted to enter a.

, groove in a record at which rests. on aturn table 5. The holder 2 ha'sa shank 6 which is adapted to be fixed inan ordinary needle holder 7 of a phonograph 8 in the conventional way. In the preferred embodiment of our invention, this shank 6 terminates. at

ashoulder or enlarged portion 9 which is preferably made rectangular in cross section and is provided at its free end with a downwardly extending point 10 which extends at any suitable angle, saydegrees, and terminates in around nose 11.- Thispoint 10 is provided with a suitable perforation,

and extend from the U at or near its middle point, through which is passed a pivotpin 12 which engages the up-turned ears 13 on each side of the end 10 parallel to the shank 6, or substantiallyso, in the usual embodiment of my invention, although of course this isnot essential and may be varied if desired. This U vtrough l l is slotted to receive a leaf spring 15 that is adapted to rub against the part 9. I

The func i n of this leaf sprin 15 is to trough 14 which runs 1923. "ser al No, 339,049.

separate theparts 14 and 9 so thatthe wire nose;.11 of the end'10l 3 is clamped in the hollow of that] b th p This wire 3. has one end fixed to a guide 1 16 so that this guide may he slid on the U 14 and thereby shift the wire 3 in the direc= tion of itsllength. This wire cannotbe so. 1

shifted'unless the parts 9 and 1 1 are brought towards each other so as tofree the nose 11 from'the wire, as indicated in: dotted lines in Fig. 1, .at whic'h time this adjustment may take place. Once this'adjustment has taken place, theparts l land 9 are allowed to separate on the' pivot 12 as an axis and then the nose 11 will cl mp the wire 3 at the desired position- This. adjustment musttake place I from time totimeaccording to the wear on suit the desires of the person playing the instrument with great ease. and facility, making the'tone either loud or soft, as desired. i 1

'In the may be varied, if desired. This wire made small enough to'fit in the ordinary groove of a phonograph recordand it wears to fit or replacement of any kind whatsoever. If

the needle 1, be "removed from'the phonograph 8 for the purposes of "adjustment, it can easily be replaced without any shifting because 1t is easy to keep the parts 1 1 and 9 inthe same vertical plane, and the needle 3 has 'no chance to turn on its axis when ad'-. 'justed. From thisitis apparent that the.

the wire when in use and the loudness of sound to be produced. It can befadjusted to V I 'preferred embodiment of our in- I vention, the wire fiis made. ofgold, but this I 'very readily and thereafter will last a long time, say several hours, without adjustment needle can beusedseveral times and at dif- I ferent times and after removal and insertion it will always present the same true edge to the record. r

In the embodiment of our invention shown in Figure 5, the structure is the same as be: fore, except that the holder 2 has an end 10 whiclris pivotally connected to the part9 by means of ears 17 and a clamping screw 18 so that .theangle betweenthe parts 9 and 14 may be varied, as desired, so that this needle may'ha've a wide range'of adjustment, if desired, and be made to fit any peculiar phonograph.

In view of the forego1ng,,the use of our mprovedneedle willbe'readilyfunderstood.'

It is placed in 211 phonograph in the usual Way and nsed in the conventional manner and from time to time removed and ad- 'jnsted, as dosh-ed, and it can be adjusted Without removal. In any position, a great many records may be" played one after another Without changing f he geedle I I Vhile We have shown a'ri d' (lesoi ihedf one embodiment of our invention it obvious that is notrestricted the fetoihii't thatit enough to; cover all structures that eonge ja :th of h lainisl, Haxiin g 151m s described our invent on,' who we claim is'zg phoiig'faph.nee'dle iooinposed' of a 23 4A phono ho den and a wyl lfe stylus, the hold I qee nee of t 9, a ts Wllh ewe-l a s gain 5& new i le ti zfllin 2 2d a sprlng tendmg to separate said parts,
